Hernia Surgery: When It Is Needed and What to Expect

A hernia can feel worrying, especially when it starts affecting your daily life. The good news is that hernia surgery is one of the most commonly performed procedures in the world, with well-established techniques and generally excellent outcomes.

Understanding what hernia surgery involves, when it is necessary, and what recovery looks like can help you feel more prepared and less anxious about what lies ahead.

What Is Hernia Surgery?

A hernia occurs when an internal organ or tissue pushes through a weak spot or opening in the surrounding muscle wall. This often creates a visible or palpable bulge, most commonly in the abdomen or groin area.

Hernia surgery, also called herniorrhaphy, is a procedure designed to push the displaced organ or tissue back into its correct position and repair the weakened or torn muscle wall. In many cases, a piece of surgical mesh is used to reinforce the repair and reduce the chance of the hernia returning.

Globally, around 20 million hernia surgeries are performed every year, making it one of the most routine surgical procedures in modern medicine.

When Is Hernia Surgery Needed?

Not every hernia requires immediate surgery. Some hernias are small, cause no discomfort, and may be monitored over time. However, most hernias do worsen gradually, and surgery becomes necessary in the following situations:

• The hernia causes persistent pain or significant discomfort.
• The bulge is growing larger over time.
• The hernia interferes with daily activities, exercise, or work.
• The hernia cannot be pushed back in (known as an irreducible hernia).
• There is a risk of strangulation, where blood supply to the trapped tissue is cut off.

A strangulated hernia is a medical emergency. If you experience sudden, severe hernia pain, nausea, vomiting, fever, or a rapidly enlarging bulge that turns red or dark, seek emergency care immediately. Recognising hernia symptoms early can help you avoid this serious complication.

Even when a hernia is not yet painful, your doctor may recommend surgery to prevent future complications, particularly if the hernia is in a vulnerable location.

Types of Hernias That May Need Surgery

Several types of hernias may require surgical repair, including:

• Inguinal hernia: The most common type, occurring in the groin area when tissue pushes through the inguinal canal. It can sometimes extend into the scrotum in men, causing swelling or discomfort.
• Umbilical hernia: Tissue protrudes near the navel. Common in infants, but also seen in adults.
• Incisional hernia: Develops through a scar from a previous abdominal surgery.
• Femoral hernia: Occurs just below the groin, more commonly in women.
• Hiatal hernia: Part of the stomach pushes up through the diaphragm into the chest cavity.
• Lumbar and flank hernias: Less common, occurring in the back or side of the abdominal wall.

The type of hernia you have influences the surgical approach your doctor will recommend.

Types of Hernia Surgery

There are three main approaches to hernia repair:

• Open hernia surgery: The surgeon makes a single incision over the hernia site. The displaced tissue is carefully returned to its proper position, and the abdominal wall defect or weakened muscle is stitched closed, often with surgical mesh for added support. Open surgery is typically used for larger or more complex hernias.
• Laparoscopic hernia surgery: Also called keyhole surgery, this approach uses three or four small incisions. A thin camera (laparoscope) is inserted through one incision, projecting images onto a monitor. Surgical instruments are passed through the other incisions to complete the repair. This method generally results in less post-operative pain, less scarring, and a faster return to normal activities.
• Robotic hernia surgery: A form of laparoscopic surgery where the surgeon operates from a console using robotic instruments. It offers greater precision and is particularly useful for complex or recurrent hernias. Robotic repairs may take longer than conventional laparoscopic procedures.

Your surgeon will recommend the most appropriate type based on the size, type, and location of your hernia, as well as your overall health.

How Hernia Surgery Is Performed

Pre-Surgery Preparation

Before your surgery, your doctor will conduct a thorough assessment to ensure you are fit for the procedure. Preparation typically involves:

• A review of your full medical history, including any chronic conditions.
• A list of all medications, vitamins, and supplements you currently take. Some, particularly blood thinners, may need to be paused before surgery.
• Blood tests or imaging to assess your overall health.
• Instructions to fast for a specified period before your procedure.
• Guidance on stopping smoking if applicable. Smoking increases the risk of infection and can impair healing after surgery.
• Arranging for someone to drive you home, as you will not be able to drive following anaesthesia.

The Surgical Procedure

On the day of surgery, you will be given anaesthesia. Open surgery may be performed under local, regional, or general anaesthesia. Laparoscopic and robotic procedures typically require general anaesthesia, meaning you will be asleep throughout.

The surgeon will then make the necessary incision or incisions, reposition the herniated tissue, and repair the muscle wall, using sutures, surgical mesh, or both. Once the repair is complete, the incisions are closed and dressed.

Simple hernia repairs can take as little as 30 minutes. More complex cases may take several hours.

Post-Surgery Monitoring

After the procedure, you will be moved to a recovery area where your care team will monitor your vital signs as the anaesthesia wears off. Most hernia surgeries are performed as day procedures, allowing you to go home the same day. More complex repairs may require an overnight hospital stay.

Is Surgical Mesh Always Used?

Not always, but surgical mesh is used in many hernia repairs. Mesh is a flexible material that reinforces the repaired muscle wall, reducing the likelihood of the hernia returning. It is particularly beneficial for larger hernias or those in areas under significant mechanical stress.

In some cases, particularly in young patients or those with small hernias, a surgeon may perform a mesh-free repair using sutures alone. The decision depends on the hernia's characteristics and your individual circumstances. Your surgeon will discuss the approach that best suits your situation.

Benefits of Hernia Surgery

For those who need it, hernia surgery offers clear advantages:

• It relieves pain and discomfort caused by the hernia.
• It prevents the hernia from worsening over time.
• It eliminates the risk of dangerous complications like strangulation.
• Minimally invasive techniques mean less scarring and faster recovery for many patients.
• Research indicates that only around 16% of people require further surgery due to hernia recurrence within 10 years of the first repair.

Recovery After Hernia Surgery

Recovery varies depending on the type of surgery and the complexity of the repair. In general:

• You can expect some soreness and discomfort in the first few days after surgery, which is usually manageable with pain relief medication.
• Light walking is encouraged from the day after surgery to promote circulation and healing.
• Most people with non-physically demanding jobs can return to work within a few days.
• Those with physically demanding roles, including jobs that involve lifting, may need to wait several weeks before returning.
• Driving is typically restricted until you can perform an emergency stop comfortably and are off strong pain medication.
• Follow-up appointments are important to ensure your wound is healing as expected.

How Long Does Recovery Take?

Recovery timelines differ from person to person. The size and type of hernia, the surgical method used, your age, and your overall health all play a role.

For laparoscopic repairs, many people feel well enough to resume light activities within one to two weeks. Open surgery often involves a longer recovery, sometimes three to six weeks before returning to full activity.

Your surgeon will give you a personalised timeline and advise you on when it is safe to resume exercise, heavy lifting, and sexual activity. Always follow their specific guidance rather than general estimates.

Risks and Complications of Hernia Surgery

Hernia surgery is considered a safe procedure, but as with any operation, it carries some risks. Being informed helps you recognise warning signs early.

Short-term risks include:

• Infection at the incision site.
• Bruising or bleeding.
• Fluid collection near the repair site (seroma).
• Temporary difficulty urinating, particularly after groin hernia repairs.
• Injury to nearby structures, including blood vessels or the bladder.

Longer-term risks include:

• Chronic pain in the groin or repair area.
• Mesh-related complications, such as migration or breakdown over time.
• Hernia recurrence, though this is uncommon.
• In men who have had inguinal hernia repair, there is a small risk of complications affecting the scrotum or testicular blood flow, though serious outcomes are rare.

Anaesthesia-related complications, including cardiovascular events, are rare but can occur. Your surgical team will review your overall health before the procedure to minimise these risks.

Activities to Avoid After Hernia Surgery

During your recovery, it is important to protect your repair and give your body the time it needs to heal. Avoid the following until your surgeon clears you:

• Heavy lifting or straining.
• Vigorous exercise, including running, cycling, or gym training.
• Driving, particularly in the first few days or while taking strong pain relief.
• Activities that put direct pressure on the repair site.
• Sexual activity until advised otherwise.
• Returning to physically demanding work before you have been assessed.

Listen to your body. If something causes pain or discomfort, stop and consult your doctor.

When to Call Your Doctor After Surgery

Contact your surgeon or healthcare provider if you notice any of the following:

• Fever or chills.
• Increasing redness, swelling, or warmth around the wound.
• Discharge or pus from the incision.
• Blood seeping through your dressing.
• Constipation or inability to pass gas that does not resolve.
• Persistent or worsening pain that is not controlled by prescribed medication.

Go to the nearest emergency department immediately if you develop signs of a blood clot in your leg, such as calf pain, sudden swelling, or redness in the leg. Also seek immediate care if you show signs of sepsis, including high fever, rapid heart rate, confusion, or shortness of breath. These are serious conditions requiring urgent attention.

Frequently Asked Questions

Is Hernia Surgery Painful?

You will not feel pain during the procedure itself, as anaesthesia is used throughout. After surgery, some soreness and discomfort are expected, particularly in the first few days. This is usually managed effectively with prescribed or over-the-counter pain relief. Laparoscopic surgery typically causes less post-operative pain compared to open surgery. Most people find the discomfort manageable and improve steadily with each passing day.

How Long Is the Hospital Stay After Surgery?

Most hernia surgeries are performed as day procedures, meaning you go home the same day. More complex repairs, such as those involving large hernias or significant abdominal wall defects, may require an overnight stay of one to two nights. Your surgical team will advise you based on the specifics of your procedure and your recovery in the hours after surgery.

Can a Hernia Come Back After Surgery?

Yes, hernia recurrence is possible, though it is not common. Research suggests that around 16% of patients may need repeat surgery within 10 years. The use of surgical mesh has significantly reduced recurrence rates. Following your surgeon's post-operative guidance, avoiding heavy lifting during recovery, maintaining a healthy weight, and not smoking all contribute to a better long-term outcome.

Is Laparoscopic Hernia Surgery Better Than Open Surgery?

Laparoscopic surgery generally offers advantages such as smaller incisions, less post-operative pain, reduced scarring, and a quicker return to normal activities. However, it is not always the most suitable option. Open surgery may be preferable for larger, more complex, or recurrent hernias. The best approach depends on your specific hernia type, size, location, and overall health. Your surgeon will recommend the technique that gives you the best outcome.

When Can I Exercise After Hernia Surgery?

Light walking can usually begin the day after surgery and is encouraged. However, more strenuous exercise, including weight training, running, and sport, should be avoided until your surgeon gives you the go-ahead. For laparoscopic repairs, this is often around four to six weeks. Open surgery may require a longer wait. Always get personalised guidance from your surgeon before resuming any physical activity.
